Question 1

Is the value of expression 2x + 3 greater than 10? (1) x > 3. (2) x < 5.

Accepted Answer

Neither statement alone nor both together are sufficient

Answer

If x > 3, then 2x + 3 > 9, which could be 10 or more; if x < 5, then 2x + 3 < 13, which could be 10 or less; together, x ∈ (3,5) gives 2x+3 ∈ (9,13), which doesn't confirm > 10.

Question 2

A company produces widgets. Did production increase last quarter? (1) Production this quarter is 5,200 units. (2) Production increased by 4% from last quarter to this quarter.

Accepted Answer

Statement 2 alone is sufficient

Answer

A 4% increase directly tells us production went up from last quarter; statement 1 alone gives no comparison point.

Question 3

What is the perimeter of rectangle R? (1) The length of R is twice its width. (2) The area of R is 50 square units.

Accepted Answer

Both statements together are sufficient, but neither alone is sufficient

Answer

Let width = w; then length = 2w and area = 2w² = 50, so w = 5 and perimeter = 2(5+10) = 30.

Question 4

Is integer j even? (1) j + 4 is even. (2) j/2 is an integer.

Accepted Answer

Either statement alone is sufficient

Answer

Both statements independently confirm j is even: j+4 even ↔ j even, and j/2 integer means j is divisible by 2.

Question 5

In a database table, are there any duplicate records? (1) The table contains 1,000 rows. (2) The primary key column has 998 distinct values.

Accepted Answer

Both statements together are sufficient, but neither alone is sufficient

Answer

1,000 rows but only 998 distinct primary key values means at least 2 records share a key, confirming duplicates.
